This article might help you out a bit. It breaks down the structure of the Gettysburg Address to a few simple steps, analyzes them, and even provides a modern example of how to use the same structure in your own work. It's not meant for fiction, but I still think it might just help you out a bit. Especially since the Gettysburg Address, apart from being one of the world's greatest speeches, is also at least 80% info dump. Done well, nobody notices. Just remember to do what Lincoln did, and tie every fact to a powerful emotion.
